Our standard high-performance Low-E insulating glass lowers energy costs, helps homes stay cooler in the summer and warmer in the winter, reducing the fading of interior furnishings and condensation. It also delivers greater visible light transmittance than tinted glass.
Add architectural interest to your windows with our divided lite options. These options include simulated divided lites (SDL) for an authentic look. They feature grilles that are permanently attached to both the interior and exterior glass and optional shadow bars that are placed between the two panes of insulating glass to provide design detail.
Grilles are available in 7/8″ widths in several grille patterns. These grilles are available in the color that matches the exterior color of the window you choose.
Safety Glass
Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass. Laminated glass is normally used when there is a possibility of human impact or where the glass could fall.
Tempered glass is a type of safety glass that has increased strength and will usually shatter in small, rounded grains instead of jagged shards when broken. It is used when strength, thermal resistance and safety are important considerations. In residential applications it’s mainly found in bathrooms, patio doors and fixed lites adjacent to doors. Toughened glass is typically four to six times the strength of annealed glass.
Obscure Glass Options
Obscure glass is used primarily to obscure views while still allowing in light. These glass options are typically used in bathrooms and other rooms where privacy and light are desired.
Delta Sandblast Glass is a moderately obscure glass with raised lines that mimic the look of cracked ice on a frozen surface.
Satin is an obscure glass with moderate privacy that has a smooth, sating look.
Rain is a directional pattern that gives the appearance of a waterfall.
Pinhead Obscure Glass is the most common and economical option.
Flute Obscure Glass offers an obscured view with modern architectural appeal. This style is great for kitchens, laundry rooms, offices and any room where a stylish touch and light are wanted, but not full visibility.

“We are impressed with the product, installation and crew. In this day and age, we are quick to criticise but forget to praise when everything goes well. The crew were efficient, fast and left everything spotless. The cost was as budgeted and the work completed on time. Besides making our home incredibly warmer, we have really noticed how much quieter it is. The street noise has decreased immeasurably.
We would be happy to recommend your company to potential customers and have already done so with the neighbours and friends.”

“Where other companies were just giving quotes over the phone, Rob from A-1 Windows agreed to give us an in-person quote. His personalised approach and excellent customer service were one of the main reasons why we decided to go with them. Mani and Ranjit were very considerate and professional and did an excellent job installing our two windows. They were careful to protect our flooring and did a thorough clean-up afterwards. COVID-19 protocols were followed, and they were in and out in record time. Overall, we are very happy with the price, the work, and our decision.”
